Use ProvisioningRequest capacity-check on Kubernetes 1.30.1+

[dgrove-oss]

As discussed in this slack thread, on Kubernetes 1.30.1 or newer, we may be able to configure Kueue with a ProvisioningRequest AdmissionCheck to leverage the Cluster Autoscaler to ensure that workloads are not admitted until there is sufficient actual capacity to run them. This should work even on fixed sized clusters by using the check-capacity.kubernetes.io ProvisioningClassName.

See https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md#how-can-i-use-provisioningrequest-to-run-batch-workloads.
